The suspect's name and the charge were made public Wednesday after witnesses who saw Davis shove Ki-Suck Han, 58, in front of the train Monday afternoon identified him in a lineup, according to police.

Han attempted to climb back up onto the platform as the train approached, a moment captured by freelance photographer R. Umar Abbasi.

The image covered the New York Post Tuesday, sparking debate over journalistic ethics and, writes the Times, raising "questions about how bystanders in the city can – and perhaps, should – behave in moments of crisis."
